IP6520 from INJOINIC, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOUT | input | Output voltage feedback pin; the output is regulated between 3V and 12V depending on the fast-charge protocol negotiated. |
| 2 | VIN | power_in | Input voltage pin with a filter capacitor to be placed close to the IC; operating input range is 7.1V to 32V, and the absolute maximum rating is 40V. |
| 3 | SW | passive | DCDC switching node that connects to the power inductor; LX voltage is limited to VIN+0.3V absolute maximum. |
| 4 | BST | passive | Bootstrap pin; the bootstrap capacitor is placed close to the BST and SW pins to provide gate-drive voltage for the high-side power MOSFET. |
| 5 | DM | bidirectional | USB fast-charge identification signal DM; the DP/DM overvoltage protection threshold is 4.5V typical and the absolute maximum voltage is 6V. |
| 6 | DP | bidirectional | USB fast-charge identification signal DP; the DP/DM overvoltage protection threshold is 4.5V typical and the absolute maximum voltage is 6V. |
| 7 | CC1 | bidirectional | Type-C detection pin CC1; CC overvoltage protection triggers at 6.0V typical, and the CC pin withstand voltage is 30V (absolute maximum 30V). |
| 8 | CC2 | bidirectional | Type-C detection pin CC2; CC overvoltage protection triggers at 6.0V typical, and the CC pin withstand voltage is 30V (absolute maximum 30V). |
| 9 | GND | power_in | Power and thermal ground exposed pad that must maintain good contact with the PCB ground. |
